SWITCH FOR CONTROLLING ELECTRIC CIRCUITS.

Application filed November My present invention has reference to aswitch for controlling electric circuits such for instance as the lampsin the different transparent compartments in a direction signal housingfor automobiles, and the improvement resides in the construction,combination and operative association of arts, a satisfactory embodimentof which is illust"ated by the accompanying drawings.

10 The figure illustrates a side elevation oi my improved switch, theparts being in section.

I have not deemed it necessary to illustrate the electric wire, but itis understood that one wire of the different circuits is connecteddirectly to the switch proper, and the other wires are connected tobinding posts which are associated with the contacts that are engageableby the switch.

The switch comprises a frame having a flat face 18, upstandingrightangular sides 19 and an arcuate top 20 connecting the sides. Thetop has an elongated centrally arran cd slot 21 therethrough. The top ispreferably of insulating material, but, as a matter of fact, the framefor the switch may be of light material. Passing through the slot 21 ofthe frame there is a push rod 22 having an outer headed end 23.Pivotally secured to the push rod 22 there are laterally extending arms24-. and 25 respectively. Surrounding each rod there is a helical spring26. The push rod 22 is influenced in an upward direction from the frameby a spring 27, suitable stop means being provided for limiting the pushrod in such direction. The outer end of the push rod is of insulatingmaterial,

but the inn r portions thereof are in the nature of electric conductors.The arms 24 and 25 as well as the lower portion of the 4.0

push red are in the nature of circuit closures,

eael. being movable to engage the contacts .28, 29 and 30 respectively.The contacts provide binding posts for the positive wires from the plateto the bulbs in the several ts in a signal casing, while a connectedbetween the switch no of the automobile.

1 rod is provided with an elongat- 2 that receives therethrough a sothat free lateral movement 1 us'h rod will be prevented.

lescrihed the invention, I claim:

u-h for controllin the electric cir- 'cin described, comprising a casingmaterial having contacts at the u on the bottom thereof, a slotted lreceived in the casing having one e: d passin through the top of thecasing, a

0 (it; (a

pin passing through the slotof the rod, and

' v end of said rod being disposed dive the contact on the bottom of theor ns influencing the rod outward of the casing to bring the samenormally out of engagement with the mentioned contact, said rod havinglaterally extending ar ns whose ends are disposed in alignment with hecon acts in the casing, and

L L sprii (r the arms and exerting a surrounci H pressure against therod to hold said arms nornmlly out of engagement with said lastmentionedcontacts.

In testimony whereof I afiix my signature. JEEGlilE-l ABEDELL TVILLIAMS.
